EU Active Substance Approvals: What the Latest Extension Means for Your Portfolio

Last reviewed: 11 November 2026

The EU has adjusted the approval periods for a batch of pesticide active substances. Most received more time; one received a clear exit signal. The practical implications are completely different, so the two groups should be separated.

Key takeaways

· 26 active substances and microbial strains have had their approval period extended, including tembotrione, acequinocyl, flonicamid and emamectin.
· New expiry dates fall between March 2027 and May 2030.
· This is a procedural extension to allow the review to continue — not a renewal approval.
· Buprofezin is different: its extension runs only until 15 March 2027, and the relevant standing committee voted in September 2026 not to support its renewal.
· For extended substances: confirm that registration documentation and supplier files cover the new expiry date.
· For buprofezin: treat March 2027 as a hard cutoff and start qualifying alternatives now.

At a glance

The safe side: extended, not re-approved

A group of active substances and microbial strains has had its approval period extended — 26 in total, including widely traded actives such as tembotrione, acequinocyl, flonicamid and emamectin. New expiry dates fall between March 2027 and May 2030.

For buyers and exporters, this means no immediate disruption: existing supply chains can continue on their current registration basis, provided the relevant documentation covers the new expiry date.

One point needs to be stated clearly: this is a procedural extension to allow the review to continue, not a renewal approval. It buys time; it does not settle the long-term status of these substances.

The risk side: buprofezin is heading for exit

Buprofezin stands apart from the rest. Its extension is measured in months, not years — only until 15 March 2027 — and the relevant standing committee has already voted in September 2026 not to support its renewal. The extension should not be read as a sign that renewal is likely.

For anyone holding or sourcing products containing buprofezin, the sequence to watch is:

1. The non-renewal regulation entering into force.
2. The deadlines for member states to withdraw product authorisations.
3. The arrangements for stock disposal.

What to do now

For the extended substances:

· Confirm that your registration documentation and supplier files cover the new expiry date.
· No other action is needed at this stage.
· Do not treat the extension as a renewal approval.

For buprofezin:

· Treat March 2027 as a hard cutoff and work backwards.
· Take stock of inventory and orders in transit.
· Check how quickly your target member states are likely to withdraw product authorisations.
· Start qualifying alternative actives now, rather than after the regulation takes effect.

FAQ

Does an extension mean the substance has been re-approved?
No. The extension is procedural and allows the review to continue. It is not a renewal approval.

Which substances received more time?
A total of 26 active substances and microbial strains, including tembotrione, acequinocyl, flonicamid and emamectin. New expiry dates fall between March 2027 and May 2030.

What is different about buprofezin?
Buprofezin is extended only until 15 March 2027. The relevant standing committee voted in September 2026 not to support its renewal, so the extension should not be read as a positive renewal signal.

What should exporters do first?
For extended substances, verify that registration documentation and supplier files cover the new expiry date. For buprofezin, review inventory and orders in transit, monitor member-state withdrawal deadlines, and begin qualifying alternative actives.
